Hot tub deck

[black2002ls]

Has anyone done a ground level deck for a hot tub? My primaty concern is support. I plan to build the frame out of 4x6's that are bolted together, as well as utilize joist hangers. That should hold hold the weight of the tub. It is an 8'x8' 6-8 person tub.

I am trying to decide what to do below the 4x6's. Initially I was going to pour piers/footings. But have been wondering if deck blocks set on 12x12 or 16x16 "pavers" would work for footings.

Anyone have any experience with this?

A concrete slab will be much better...

It would, but would require some extensive dirt work, and from what I have been told, all of the local concrete companies have a 5-7 yd minimum.

You just have to pay their minimum of what a 5 yard pour would be. It doesn't have to use that much.

Yeah, I'm not keen on paying an additional $500+ in materials I'm not going to use! My price as a major contractor at work is $100/yd. I would assume it would be more expensive for a private job

If a slab is out of the question, then I would definitely do concrete footers at least 10-12" in the ground. Hot tub is fiberglass so ground shift will cause major issues if you just put it on pavers....

Dont forgot about the water that drains undernearth. Slope ground where ever you set the hottube.

It is on the edge of my new patio. The plan is to digvthe holes for the piers and set it 3-4" above grade, rake the dirt out, weed cloth, and stone to prevent weeds from coming up through the deck and the ground from washing out.

Once I get my grill station set, this is next on the list. We have a hot tub waiting for us, just need a place to put it!

So ideally, you'd have a sloped concrete slap? That's kind of inconvenient. What about propping the tub up on something like cinder blocks or cut 4x6's. I've got the concrete, but its not sloped. And I want a hot tub

Just enought to push the water away from the hottube. 3/4 " fall maybe depend on the size of the slab.

How big is your pad? I wouldn't be too concerned about drainage if it is a small pad. 8'x8' if it is level, you will be fine.

3/4" is excessive for most pads that small. As I mentioned above, if it is a dedicated pad for the tub and not much bigger than your tub itself, it isn't super important, make sure the tub frame isn't dorectly on the pad or that it gets air circulation to dry any standing water. Even in a down pour, if it is flat it isn't going to hold much water. I wouldn't go any steeper than 1/8-1/4"/ 4 linear feet, and would most likely lean towards 1/8". More important would be the ground around the pad having proper drainage

Unless the tub sit right on the pad. Wood rot if you do have water sitting under the tub.

Why are you asking about his hot tube?

I believe its a 12'x24' area of concrete. Just the back porch. Covered by the roof, so no problem there. Propping up the tub about 6-8 inches off the ground wouldn't be enough?

If it is covered patio, was it poured with the house? If so you should have sufficient slope on it for drainage. I wouldn't go 6-8" above the concrete, I would lay a 2x4 flat and shim to make it all level.
